Setting Transaction IP Velocity Filter

Authorize.net allows you to define the number of transactions received from the same IP address within the course of an hour. The default value in the gateway is set to 10 transactions per hour. This setting, while helpful for fraud detection, does not take into account the number of transactions processed at the box office and needs to be increased.

1. Open your online gateway to Authorize.net and select Fraud Detection Suites in the right column.

   

2. Under Card Testing Settings select Transaciton IP Velocity Filter

   

3. In the Transaction IP Velocity Threshold section of the page increase the Allow transactions from the same IP address per hour value.

   This value should be set based on the number of transactions your organizations processes in the office per hour during peak sales times. Depending on the size of your organization this may mean 50, 100, or possible 500.

   

4. Click the Save button at the bottom of the window.
